A model to compute the repointing time of a satellite antenna on two overlapped visibility circles

File Information
Description

Given the orbital parameters of a satellite equipped with a steerable antenna and the locations of two ground stations whose visibility circles are overlapped (e.g. Matera and Svalbard), the model is able to compute the time spent by the steering mechanism to repoint the dowlink antenna from the first to the second station.

Due to the overlapped visibility zones, this repointing time has to be taken into account for the degradation of the overall dowlink performances.

Required Products Aerospace Blockset
Mapping Toolbox

EML initialization of 'lat' and 'long' variables removed: this fixes some errors while moving toward most recent MATLAB releases.
